Hyper Human Applications

Research Contents

We are promoting research by participating in joint industry-academic projects with companies for on-line measurements and control at manufacturing sites, and joint projects with biomedical researchers for behavior mining of biological behaviors that are too rapid for the human eye to detect. We will establish hyper-human technologies as advanced technologies for better human life through joint researches in various application fields.

Real-ime Quantification of Mice's Scratching Behavior

In this study, we developed a novel real-time motion analysis system for detecting the scratching behavior of laboratory mice in long-time experiments, which enables automated behavior quantification for new drug development in diseases such as atopic dermatitis and so on. This system can detect quick movements of laboratory mice, such as scratching, by introducing a specially designed high-speed vision system INCS1020 that can calculate the frame-to-frame difference at a frame rate of 240 fps (frames per second).

Quantification algorithm was also implemented for distinguishing scratching behavior from other behaviors. In fact, we evaluated the effectiveness of our system by demonstrating the experimental results of scratching behavior detection during 20 minutes observation of several ICR mice administered with compound 48/80 to induce frequent scratching. The following graphs are examples of the results in 1 second with regard to scratching. (g(t):frame-to-frame difference feature, C'g(t):detection result).
